    109. 

  109.       <p>碳水、蛋白质、脂肪、纤维素的代谢评分反映了你的菌群对这些营养素的处理能力。如果纤维素代谢评分低，说明你的产SCFAs能力不足——需要增加膳食纤维。</p>

    113. 

  113.       <p><strong>铁缺乏</strong>是老年人最常见的营养问题，但年轻人（尤其是月经期女性）也不少见。铁缺乏会影响免疫功能和认知。锌缺乏则与免疫功能受损、味觉减退、伤口愈合慢相关。</p>

    127. 

  127.     <p><strong>该怎么办：</strong>从低剂量膳食纤维开始（每天15g），逐步增加到25-30g。突然大量增加可能导致胀气——让菌群慢慢"适应"。</p>

    132. 

  132.     <p><strong>该怎么办：</strong>增加富含铁的食物（红肉、菠菜、豆类）和富含锌的食物（牡蛎、坚果、全谷物）；考虑补充益生菌改善吸收环境。</p>

    137. 

  137.     <p><strong>该怎么办：</strong>增加富含色氨酸的食物（火鸡、鸡蛋、奶酪、坚果）；补充含有乳杆菌的益生菌（乳杆菌可促进色氨酸代谢为血清素）。</p>
